She often secretly helped Phineas' army Xros Heart and later joins. In the 2nd half of the Digital World Adventures, Isabella gets a new outfit again. (Making her the only character with more then two sets of clothes), her character is similar to Nene from Digimon Xros Wars. Isabella is the character with the 2nd most development. (The 1st being Phineas)

Digimon Collection

A new series based on Xilam/Gaumont's Oggy and the Cockroahces. Izzy always has a quiet day until three cockroaches named Dee Dee, Kenny and Joey. Izzy's best friend, Iza tries to get new plans to get rid of the trio while Rob, the neighbour of the two always plummets the duo (which normally happens off-screen. The only hint is the punching sounds and the duo screaming) but the cockroaches is their fault but made the duo the "suspect"

Slapstick humor is kept to maximum while dialogue is set to minimum to no dialogue. Unlike other slapstike cartoons, this even drops busses, trucks, submarines and planes while dropping anvils and pianos are still made here but this is what we call "advanced slapstick humor". The show is originally slated to begin on January 2012 but Oggy and the Cockroaches was renewed with a Season 4.

These are episodes from Season 31. In Little Miss Uncontainable, it is revealed Isabella has Mad Tummy Disease, which is a disease that gives younger children abnormally large stomachs until age 8 1/2. If you eat undercooked tacos after having the disease it's bad for your stomach, which is what happens to Isabella in Isabella's Tummy Ache.

Relationships

She has romantic daydreams about Phineas and believes she will one day marry him or Ferb, but she never says that to him. She married Phineas in Phineas & Isabella's wedding and had April as their daughter.

Isabella likes Adam. She, along with Phineas, Ferb & Candace finds Adam funny and thinks of him as their brother. She was fastinated with the way Adam designs his weapons. In Don't go to sleep, Phineas & Isabella got hit by Adam's tranqulizer dart and got put to sleep.

Isabella is best friends with Ferb, likely because he's the stepbrother of her crush, although she seems to get annoyed when Ferb goes with Phineas goes. Along with Candace, she has outright stated that Ferb is Phineas' stepbrother ("Rollercoaster"). Unlike her time with Phineas, Isabella shows no romantic interest in Ferb although she does like him. However, after time-traveling to the future, she learned that she might marry either Phineas or Ferb ("Phineas and Ferb's Quantum Boogaloo"). Upon this discovery, Ferb turned around and winked at Isabella, who was stunned at the possibility that she may marry someone else other than Phineas. This may indicate that Ferb may harbor a bit of affection for Isabella, or that Ferb just fancies himself a ladies' man ("Thaddeus and Thor"). It is also possible he was simply teasing her. Ferb is slightly irritated and gets mad when Phineas gets all of Isabella's attention and praise for being a superhero ("The Beak"), but it can be just the thought of him being the one who controls the lower half and saves Danville from the falling sign, but Phineas gets all the attention.
When they were stranded on the uncharted island, Ferb listened while Isabella talked about Phineas not noticing her and offered her a handkerchief when she started crying. He knows about Isabella's crush on Phineas and he also walked away when Phineas came to leave them alone. He may might not have any affection to Isabella however he knows he might get married with her. ("Phineas and Ferb Summer Belongs to You!", "The Doof Side of the Moon"). It is most likely that he does not have affection for Isabella since he has more affection for Vanessa Doofenshmirtz ("I Scream, You Scream"). Ferb has also demonstrated awareness of Isabella's affection for Phineas; after Ferb helped Phineas throw a party for Isabella, when Phineas offered her ice cream with Ferb, he left to have Phineas and Isabella have some alone time together. Isabella was pleased and both bumped fists. ("Happy Birthday, Isabella") It is very plausible that Ferb did this because he knows that either he or Phineas will marry Isabella and he doesn't have any romantic feelings for her.

In the episode Phineas & Ferb go to South Park, Kyle Broflovski grows a huge crush on Isabella, and faints after Isabella says her catchphrase to him, Stan, Cartman & Kenny. She eventually develops a romantic relationship with Kyle, all while Cartman makes fun of them, saying "You two are like Stan & Wendy if they were Jews!". The two can't handle Eric's mockery & punch him. Kyle & Isabella eventually break up & Kyle admits he was having a lot of fun with Isabella.
